Title: Knitting machines, knitting methods and knitted articles
IPC: D04B9/26
Filed: 1951-07-05
Abstract: 761,966. Knitting. LOMBARDI, V. July 5, 1951, No. 16011/51. Class 74 (2). Oppositely rotating " main " and reverse cam rings 10, 41 impart to the needles 7 " forward " and " reverse " knitting waves, travelling in opposite directions, the " reverse " knitting waves being imparted by the action of cams 40 on previously radially projected butts 38, 38b or 38c, on arms borne by the needles, or by jacks associated therewith, and housed in the needle tricks. The needles take wrap yarn fed during the forward and return swings of wrap yarn feeders 15 carried on a stationary dial 12. In Fig. 1, the butts 38 are at the ends of resilient arms 67 of the jacks 35, which arms are held down in the cylinder tricks by cams 60, or are flexed about a fulcrum point 390 by a cam 59 to bring the butts 38 into the paths of the cams 40. In Figs. 16 and 17, the resilient arms 67a or 67b carry the butts into the paths of the cams 40, except where restrained by cams 60. In Fig. 18, jacks 35c are rocked about point 75 by cams 59c and 60c, to bring their butts into and out of the paths of, cams 40. The swing of each wrap yarn feeder covers part of the swing of each adjacent feeder and the feeders are swung by pinions 17 and racks 18, pins 19 of which follow cam grooves 20, 21, 23, 24 in a rotating cam ring 43, under control of a pattern drum. The needles are advanced into the range of the knitting cams by jacks 25 pushed out from inoperative position by cams 28 into the path of advancing cams 30, certain of the jacks being pushed in again, before they reach the associated cam 30, by pushers 27 selected by other pattern drums. A hollow 71 on each cam 40 relieves friction when the arms 67 of any jacks 35 are swung out while a cam 40 is passing. Main yarn is supplied from feeders 48 and may be inlaid by means of inlay cams; co-operating butts are provided on alternate needles and the inlay cams raise to tucking height any such needles which have not been raised to knitting height by the cams 30. Fabrics.-Fig. 5 indicates schematically main yarn knitted in jersey loops in courses 76-83 and wrap yarns knitted in diamonds 85, alternate wrap yarn feeders being active. In Fig. 8 red and blue wrap yarns say, are fed by alternate and intermediate wrap yarn feeders respectively and knitted in, where indicated, between successive courses 86-92 of white main yarn. In Fig. 13 course 96-105 of main yarn are knitted (zig-zag lines) into jersey loops outside design areas and are inlaid (dotted lines) in such areas between wrap courses knitted in accordion stitch. In Fig. 28a indicates a fabric which may be produced when active wrap yarn feeders, spaced ten needles apart, have a swing including twelve needles, enabling a full intarsia fabric to be produced. In Fig. 30 main yarns 116, 117, 118, 119 are knitted where indicated by zig-zag lines and inlaid where indicated by straight dotted lines the remaining zig-zag lines indicating wrap yarns fed by forward and return swings of the feeders and knitted in. Specification 762,012 is referred to.

Title: Improvements in and relating to power energised braking or decelerating apparatus
IPC: B60T13/06
Filed: 1936-06-09
Abstract: 476,504. Brakes. LEITNER, H. June 9, 1936, No. 16162. [Class 103 (i)] Braking - apparatus comprises a direct braking branch and a power braking branch operated by a common pedal or the like through a floating lever the power branch being energized by a clutch put into operation by a member connected at one end of the floating lever, the other end of which is connected to the pedal and an intermediate point to the direct braking branch, the arrangement being such that the ratio between the pressure applied to the clutch and that applied to the direct braking branch does not exceed 1:2. As compared with apparatus such as described in Specification 467,184 in which the pedal is connected at the intermediate point in the floating lever there is the advantage that the magnitude of the direct pull applied to the brakes and of.the total pull is considerably increased without corresponding increase in the pressure applied to the clutch the pull of which on the brakes may be amplified by suitable means. The floating lever 1 is connected to the pedal 3, 4 at 2 and at an intermediate point by a link 5 to an arm 6 on a rock shaft 7 having mechanical connections to the brakes or to the operating lever of a master cylinder of a hydraulic brake system. The other end of lever 1 is connected by link 9 to the operating levers 11 of a disc clutch which are adapted to slide the driven member 13 of the clutch on an extension 12 of the gear box 10 of a motor vehicle into engagement with the driving member 16 secured on the vehicle driving shaft. The clutch member 13 applies a pull to the brakes through a winding drum 17, cable 18, an amplifying lever 20 and a link 19 connected to the arm 6. In a modification, the lever 20 is in a vertical plane and the links 5, 19 are connected to the arms of a double-armed lever on the shaft 7. The lever 20 may be dispensed with, the. amplification being obtained by lengthening the lever 6. A strong spring or a hydraulic transmission device may be interposed in the connections from the pedal to the clutch. The arrangement may be such that a degree of direct braking is effected before the clutch becomes operative or the clutch may come into operation first.

Title: Musical top
IPC: G10F1/06
Filed: 1956-05-25
Abstract: 806,488. Musical top. FUCHS, F. May 25, 1956 [Jan. 27, 1956], No. 16216/56. Class 132(3) [Also in Group XXXVIII] A musical top comprises a mechanism operated as the top rotates to produce sounds by blowing air through apertures having reed-like elements and incorporates a cam-cylinder device co-operating with the sound producing means and including two cam cylinders arranged diametrically opposite one another on either side of the axis of the top. The top comprises lower and upper halves 1 and 2 mounted on a sleeve 6 whose lower end rests on a ball bearing 10 in the lower end 11 of a tube 8 which is mounted on a stationary base 3. The upper end of tube 8 has a cap 9 which forms a bearing for sleeve 6. The top is rotated by pushing down a knob 4 carrying a spiral rod 5 which engages a journal 7 in the upper end of sleeve 6. A preferably plastic base plate 22 is seated in the lower half 1 and has preferably integral projections 23 with air passages 24 corresponding to the number of notes. Reeds 25 are fixed under these air passages whose upper ends are covered by flaps 26, 27 pivoted on shafts 31 and 35 respectively and biased to their closed positions by springs 29 engaging their outer ends. Each flap 26 has, at its inner end, a nose 32 projecting into the path of cams 33 on two cam cylinders 14, 15 so that, as the cylinders rotate, selected flaps are opened. Flaps 27 are similarly operated by the cams through pressure members 34 pivoted on shaft 31 and engaging the inner ends of the flaps 27. The cam cylinders 14, 15 are mounted on shafts 19, 20 each supported between two brackets mounted on plate 22. Pinions integral with cylinders 14, 15 engage pinions 16, 17 mounted on a shaft 18 on either side of a worm wheel 13 which, as the top rotates, is driven by a worm 12 pressed on tube 8. The sound is produced by air entering the top through any air passages 24 which happen to be open and out through apertures 38.

Title: Gas injectivity or productivity profile logging
Inventor: WOODWARD CHARLES DON
IPC: E21B47/10
Filed: 1969-03-28
Abstract: 1,218,144. Measuring permeability of earth in situ. TEXACO DEVELOPMENT CORP. March 28, 1969, No. 16265/69. Heading G1S. A known method of and apparatus for measuring the permeability of earth formation in the side wall of a bore hole comprises pumping gas down a pipe to a position near the bottom of the hole, pumping gas down the bore space surrounding the pipe, and determining the position of the interface where the two gas supplies meet in the bore by using a radiation detector to measure the injected radio-activity in one or the other of the two gases. By varying the gas flow in the pipe and the gas flow in the annular space surrounding the pipe but at the same time keeping the total gas flow constant, the position of the interface maybe raised and lowered in the bore, and by measuring the rates of the two streams the permeability or leakage through the side wall of the bore hole may be determined. A similar system may be employed for gas leaking into the bore hole from the surrounding strata. In Fig. 1 of the present Specification a borehole 12 is topped by a cap 11 and air is injected into the hole through a pipe 18 and also through a pipe 15 extending right down the bore. This divided air stream flows downhole and forms an interface whose position is determined by lowering a detector pipe 25 attached to a pipe 26. One of the air streams contains a tracer element such as a non-radio-active halogen which is withdrawn up the pipe 25 and passed through a flexible hose 36 to a halogen detector 37, Fig. 2. The interface may be moved vertically of the borehole by varying the rates of flow of the air streams whilst keeping the sum of the rates constant so that a record or log of the rates of the two streams may be obtained and the quantity of the halogen togged gas leaking into the soil at different positions be determined. Where gas leaks into the borehole from the soil then the gas divides into two streams which are drawn up the borehole, and one of the streams is injected downhole with a detectable tracer element. The gas stream are then sampled as they pass to the surface and the interface and permeability thus determined as before.

Title: Magnetic flip-flop devices
IPC: H03K3/45
Filed: 1959-05-12
Abstract: 868,914. Circuits employing saturable magnetic elements. ALADDIN INDUSTRIES Inc. May 12, 1959 [May 16, 1958], No. 16278/59. Class 40 (9). A pulse-halving circuit comprises a square loop core 34 which is switched to saturation by clock-pulses applied to a winding 35 to produce an output in winding 37 and when switched, offers the low impedance of a winding 36 to permit charging of a capacitor 66 which discharges after every other clock-pulse to reset the core. The clock-pulses are also applied to a linear transformer 56 the output winding 60 of which provides the charging voltage for capacitor 66. Charge is not accumulated on capacitor 66 when core 34 is being switched by a clock-pulse as winding 36 has high impedance, but is accumulated in response to the next clock-pulse when core 34 is not switched and winding 36 has low impedance. Discharge of capacitor 66 resets 34 as soon as the clock-pulse ends. To increase the width of the output pulses these may be applied to a square loop cored transformer reset by the clock-pulses (see Fig. 4, not shown).

Title: Process for obtaining photographic colour separation records
Inventor: COOTE JACK HOWARD
IPC: G03C7/26
Filed: 1947-06-24
Abstract: 638,308. Colour photography. BRITISH TRICOLOUR PROCESSES, Ltd. June 24, 1947, No. 16638. [Class 98 (ii)] Colour separation records are made from an exposed multilayer negative having differentially sensitive silver halide emulsion layers on the same side of a support by developing the outermost layer without affecting the latent image in the underlying layer, printing on to a separate element using radiation to which that element is sensitive but which is without effect on the underlying layer or layers of the multilayer negative and developing that element; chemically removing the negative image in the outermost layer, repeating the process for intermediate layers, if present ; and, finally, develop-. ing the negative image in the innermost layer. Preferably the emulsion layers of the original multilayer negative are separated by thin interlayers of gelatine. The requisite control in the processing operations is obtained by use of loaded developers followed by acid stop baths and silver removing solutions whose action is restricted and then rapidly stopped when required. Infra-red sensitive elements may be used for the positive records and infra-red radiation, which has no effect on the coloursensitive layers, used for printing these. Complete sets of either negative or positive colour records may be made from the first produced records. Two examples, both directed to the processing and printing of a three-layer blue-, green-, and red-sensitive film, describe the use of hydroquinone developers loaded with sodium sulphate or with glycerin; and silver removing solutions of acidified bichromate in a mixture of water and industrial spirit, and of a mixture of potassium ferricyanide, sodium cyanide and ammonium bichromate in aqueous glycerine, respectively. Application of the method to other three-layer films and to two- and fourlayer films is indicated. Specification 560,373 is referred to.
